// NOTE: The only assertion right now is:
// * toBe

// HOW TO USE:
// 1. Define your assertions.
/* 
  const result = add(10, 1);
  const expected = 11;
*/

// 2. Call the test function:
/* 
test('Should be able to add two positive integers', function addTwoPositiveInt() {
  const result = add(10, 1);
  const expected = 11;
  assert(result).toBe(expected);
});
